As a part of preparation for monitoring our WIndows Server 2008 R2 using SNMP and Nagios we had to add SNMP Services to few systems which didn’t have it yet. So, based on that fact I thought it might be nice to capture all steps involved in adding SNMP to Windows Server machine. Here you can see steps, screenshots and short description how to achieve that.

Whole idea for that article came from real environment. At home I have DrayTek Vigor 2850n as my broadband router (and in fact it is really nice piece of equipment). Same time I’m using some Cisco equipment located in remote Lab for testing purposes. Remote Lab is connected to Intrenet and before to get access to devices and systems located there I was using EzVPN. However, as Lab has Cisco ISR as main router I thought, why not to establish L2L IPsec between my home network and remote Lab. Now, question how to do that. I have DrayTek on one end and Cisco ISR on the other. After few attempts, mis-configurations and troubleshooting it did work quite well in fact. So, here it is.

Here is what needs to be achieved:

Equipment available:

Cisco ISR 2811 – on the left side of the diagram – internal network 10.255.0.0/24

DrayTek Vigor 2850n – on the right side of the diagram – internal network 10.130.1.0/24

Goal:

Establish IPsec VPN Tunnel between Cisco and DrayTek to make communication available between 10.255.0.0/24 and 10.130.1.0/24.

Despite all reservations to iPad as a device which might be useful in day-to-day IT Pro activities (was thinking about it more as a toy than tool) I found it really handy after some time. One of main reasons I found iPad cool IT tool was ability to connect to Cisco console port and configure Cisco devices.

Yes, it is possible to have Cisco console cable which connect to iPad and application which allows to configure Cisco via Console from iPad 🙂

In one of the previous articles I did quick overview How-to Install vSphere Hypervisor ESXi 5 on VMware Workstation 9. One of the reasons I did that in my Lab environment was to run Cisco Nexus 1000v with NX-OS on it and evaluate this operating system and how it can integrate with other products. So, here is quick overview how to make Cisco Nexus 1000v happen on vSphere ESXi.
